Fill in the scene name, a path to where the image is to be saved, and the fidelity/offset options.
a. Fidelity: How many cave walls are used. Far left - less walls, better performance, Far right - more walls, worse performance
b. Offset: How much to nudge the walls away from the edge.
If you don't use S3, make sure the storage type is set to User Data and ignore the S3 fields.
